Permission "create macro" too generic

The "create macro" permission is exposed by gmap_macro_builder.module. First it is name too generic, and could conflict with other module permissions. Although Drupal shows permissions on the admin interface as if they are module specific, they are in fact not, and span across modules. Your modules also use core permissions :) I'd suggest to name the permission "create gmap macro" or "create google map macro" or something like that.

I can provide a patch if there is a permission name decided.
